COMPENSATING PIPE-JOINT.

SPECIFICATION forming part of Letters Patent No. 765,484, dated July 19, 1904.

Appiimion filed July 31, 190s.

To all whom it may concern,.-

Be it known that I, LUDwTG HooHsrEIN, a subject of the Emperor of Germany` residing at Dietrichsdorf, near Kiel, in the Empire of Germany, have invented certain new and useful Improvements in Compensating lPipe` Joints, of which the following is a full, clear,

and exact description.

This invention relates to that class of balanced compensation devices for pipe-conduits in which the balance is obtained by the use of two stuffing-boxes situated at either end of the compensating pipe; and the object of the invention is to dispense with the slotted compensation-pipe now in use, as well as the casing which forms a water-space about the same. Atthe same time it is intended to prevent the eddying of the steam, water, or air which occurs inthe circular casing, as by the present invention the steam, &c., is given an impetus which is directly in line with the new direction to be given to the stream.

A further object of the present invention is to lprovide a device which shall be simple in construction, durable in use, and of which the parts are always accessible for inspection and repairs.

With these and other objects and advantages in view my invention consists in the novel construction and combinations of parts to be hereinafter described,and finally pointed out in the claims.

In the drawings accompanying the specification, in which similar characters of reference designate identical parts throughout the several views, Figure 1 is a horizontal crosssection illustrative of a preferred form of my invention. Fig. 2 is a side elevation of a slightly-different arrangement. Figs. 3 and 4 are elevations of forms of the invention which are intended for approximately rectilinear pipe-conduits. Fig. 5 is an elevation of a modification in which the compensationpipe takes the form of a valve. Figs. 6 and 7 are a plan and elevation, respectively,of the application of my device in the forms shown in Figs. l and 5, respectively.

In the drawings, c designates a compensation-pipe, which is secured at either end to suitable stufHng-boxes a a. Intermediate of Serial No. 167,706. (No model.)

these stuffing-boxes the branch pipes of the compensation-pipe are arranged inclined in the direction of the entering fiuid. The two stuffing-boxes, which are'of equal diameter, are connected by ties for the purpose of relieving the pressure on the pipe, said ties comprising bolts secured between suitable perforated collars on said stuffing boxes. For taking up the expansion it is immaterial whether the compensation-pipe moves in the fixed stufHng-boxes or the stuiing-boxes connected by the ties slide over the fixed compensation-pipe, as shown in Fig. 2. In some cases it is preferable to have the compensationpipe and the two stulng-boxes connected by the ties move simultaneously with relation to one another, as shown in Figs. 2 and 4.

In Fig. 2 the compensation-pipe is provided with a collar-that is to say, it is fixed-while the two stuffing-boxes t et slide over the same. The stuliing-box a may be extended in the form of a closed pipe.

As shown in Figs. 3 and 4, the compensation-pipe c and the stuffing-boxes a a are movable in their relation to each other.

In some cases a valve is placed in the compensation-pipe c, as shown in Fig. 5.

As has been stated, Fig. 6 shows the application of the form shown in Fig. l, the fluid being distributed equally between two receivers. In Fig. 7 is shown the application of the device disclosed in Fig. 5. In this case the stufiing-box a' acts asavalve f. The part of the stuffing-box a' extended as a pipeconduit is,.on the other hand, closed near the valve g. The xedpoint of the pipe-conduit is near the valve L. The valves f g /t are directly attached to the boilers, as shown.

Having thus described my invention, I claim y IOO other, a pipe fitting in the said boxes, and open at both ends, and conduit-pipes in communication with said pipe, said two boxes being connected with said conduit-pipes, substantially as and for the purpose described.

3. In a compensation device for pipe-conduits, the combina-tion with two stuiing-boxes connected with cach other, a xed pipe fitting in the said boxes and open at both ends, and conduit-pipes in communiction with said pipe, said two boxes being connected with and movable on said conduit-pipes, substantially as and for the purpose described.

4, In a compensation device for pipe-conduits the combination with two stuffing-boxes connected with each other of a valve-casing forming a tixed pipe fitting in the said boxes and open at both ends and conduit-pipes in communication with said fixed pipe, the two boxes being connected with conduit-pipes substantially as and for the purpose described.

5. In a compensation device for pipe-conduits, the combination with two stuing-boxes connected with each other or' a pipe fitting in the said boxes open at both ends, and provided with pipes branching off from the same substantially as and for the purpose described. In witness whereoil I have hereunto set my hand in the presence of two subscribing witnesses.
